I have a cactus collection, two of my larger ones have scale, i have tried several natural methods that seem to be ineffective, please offer any and all suggestions. Also i have a 30 year old poneytale palm that repeatedly gets mealy bug, have used several treatments, any suggestions again on something extremeley effective on these resilient vampires would be greatly appreciated.
If you can source cryptolaemus ladybirds. they will devour your meallybug with gusto. Scale are my personal bain. Springtime is the oportunity to nail them when thay are young and sensistive. I feel its not best to recommend isecticides
